Ready to add an Optic cut to your Smith and Wesson M&P? (No loaded chamber indicator models or Shields) Well here you go! When milling for your optic you blow out the factory rear sight location, so you can either add a Glock rear sight dovetail in front or behind the optic, or run no rear iron sight. If you are sending in your slide for a glock dovetail you must send the sight with your slide so we can mill the dovetail to be as tight of a fit as possible for your sight. Included is single color cerakote refinish of the slide, iron sight mounting if you send them, and optic mounting.
